<SilverFox> why is kmath an op here?

<FluffyFoxeh> cats!
<UmbralRaptor> Obviously egg needs to provide the next link.
<UmbralRaptor> Iskierka, egg: I have questions about the airflow around the cow's legs. Especially the front ones.

<egg|zzz|egg> UmbralRaptor: you're seeing a slice through the middle of the cow, which is why you see the effect of the legs downwind of them (but you directly see the snout shock)

<egg|work|egg> yeah

<whitequark> well, rust is pretty terse

<egg> ferram4, lamont, et al.: any idea for an adjective to say that a burn is in an inertially fixed direction (e.g. spin-stabilized), or to say that to the contrary it tracks the Frenet trihedron?

<ferram4> egg: Fixed in inertial space?
<egg> I guess
<egg> past 1000 downloads of Cayley already Ꙩ_ꙩ
<bofh> Not bad. Anyway I should probably actually read that paper now that I have time :P
<Qboid> bofh: egg left a message for you in #kspacademia [27.07.2017 18:23:06]: "http://imgur.com/a/XC6iL"
<bofh> Ooh, very not bad.
<bofh> You're doing grav assists thru all outers incl. Pluto?
<bofh> LOL \DeltaV Expended: NaN m/s
<bofh> I, erm, don't think so.
<egg> bofh: uh, that's the Sun-Earth-Moon system
<egg> it's outer in that it goes outside the Moon's orbit
<bofh> I was looking at the frame selection.
<egg> hah
<egg> bofh: I wonder whether you could moon-assist your way on the way out, making an even cheaper outer transfer
<bofh> That's a good question, actually. Like the moon's gravity well *is* fairly non-negligible...
<egg> ... or even eject yourself via an inner resonance, and then come back :D
<egg> bofh: in stock KSP+principia I can fairly easily get a ballistic capture by inner transfer, but I can't seem to do that with RSS (an outer transfer is surprisingly easy to get though)
<egg> (I can get an inner transfer with RSS, but it doesn't ballistically capture)
<bofh> (Ahh)
<bofh> LOL ejecting oneself via resonance is the goofiest approach to deorbiting oneself.
<bofh> Huh, I wonder how precise one can get a resonance ejection time to be for a given orbit. Since that seems like it *might* be practical in some weird cases?
<bofh> 17:40 * Qboid gives bofh & Fiora a spectrometer
<bofh> hey thanks that's very useful :p
<Fiora> i want a mass spectrometer
<Fiora> preferably handheld
<UmbralRaptor> mass specs are cool
* egg wrote Objective-C for the first time today
<bofh> my condolences
<egg> (for a while failed to understand why clang-format was choking on my code: it was because I was accidentally writing Swift because looking at the wrong Apple docs :-p)

* NCommander sends a message to egg but screws up the syntax and crashes NSWorld
<egg> s/NCommander/NSCommander/
<Qboid> egg meant to say: NSCommander: cayley's out, icymi
<egg> hah
<NCommander> egg, .... well played .....
<NCommander> >.>;
<NCommander> That's probably the best pun I've ever seen of NCommander :P
<egg> NCommander: Cayley *is* out though :-p
<NCommander> egg, I saw. I haven't been playing KSP for two weeks so I'm just getting my mods up to date
<egg> also Cayley comes with a reminder to update once the new moon comes, so I won't need to nag anyone again :-p
<NCommander> egg, so principia releases every new moon?
<egg> if you happen to be southeast of Nashville, Tennessee and playing KSP at the time, the reminder will appear in your UI and then the sun will go dark :D
<egg> NCommander: yup
<NCommander> egg, I'll be SE of Nashvile in a few weeks
* NCommander is moving to Dallas and will pass through there
<NCommander> egg, there's a star wars joke in here somewhere
<egg> well if you're there at the time of the eclipse and you're playing KSP, you'll see the reminder and the eclipse at the same time :D
<egg> NCommander: we release on the new moon, and the releases are named after dead mathematicians
<egg> the releases do not have numbers
<NCommander> egg, sooner or later, you're going to run out of dead mathematicians
<egg> so the next release is Чебышёв
<NCommander> egg, guess we have awhile before you run out of Russian ones
<egg> then Cesàro, Chasles, 陈景润, Chevalley, and that brings us to the end of 2017
<egg> 2018 will start with Christoffel, though we're not sure of the full list for 2018 yet
<NCommander> I'm still waiting for "World Dominance" :)
<egg> bofh: that Dante comment reminds me of the "honi soit qui mal y pense" in the Apollo guidance code
<bofh> egg: oh god link?
<NCommander> egg, link please
<bofh> I think I've seen this before tbh
* NCommander has read some of the AGC source code but didn't see that
<bofh> YEP
<bofh> Still amazing.
* NCommander finds most of the AGC design to be both amazing and elegant
<bofh> LOL
<egg> there's also the inevitable # TEMPORARY, I HOPE HOPE HOPE
<NCommander> bofh, NASA has always had a sense of humor "Attach Orbiter Here. Black side down"
<bofh> egg: every codebase has one of those
<Iskierka> "see if he's lying"
<Iskierka> this is how you know the code review was entirely black-box testing
<egg> bofh: but rarely does the codebase live long enough for it to have been temporary for so long
<Iskierka> " ASTRONAUT: NOW LOOK WHERE YOU ENDED UP"
<NCommander> It still amazes me we went to the moon on less processing power than a 8086
<Iskierka> "FLAGORGYTCINTPRET# DIONYSIAN FLAG WAVING"
<Iskierka> that whole thing what
<NCommander> At least there's no soviet russia jokes
<NCommander> "In America, we land on the moon, in Soviet Russia, moon lands on you :P"
<bofh> NCommander: egg: http://i.imgur.com/xvajBRu.png from Voyager Magnetometer data processing code
<bofh> (vgrmag/source/ibm/datamgr.for)
<NCommander> oooh fortran
* NCommander notes it's cool that we live in the future and can look at the source code to AGC on github
<bofh> Yep, indeed.
* NCommander was kinda sad that the ISEE-3 restart program failed
<NCommander> I was following that rather in-depth at the time
<NCommander> I suppose we're lucky Test Flight doesn't fully simulate loss of fuel tank pressuraization due to time
<bofh> NCommander: it could yet succeed, but yeah.
<bofh> NCommander: much like the last STEREO-B recovery attempt, which hit a similar fate for now.
<NCommander> bofh, I missed that one
<bofh> "With the limited data available, the team formulated a plan to attempt a recovery and stabilize the spacecraft pointing. The attempt was not successful. The limited data available during the recovery attempt revealed that STEREO-B came close to achieving a stable orientation, but one set of thrusters on-board may have performed abnormally, possibly due to frozen propellant and ultimately spun the
<bofh> spacecraft back up into an uncontrolled state."
<NCommander> bofh, so far, the only major spaceshipr ecovery I know was the japanese probe to Venus that blew an engine
<NCommander> and had to go around the sun twice to get a lower velocity intercept
<bofh> oh, so STEREO-B was uh
<bofh> so the ring laser gyro on it failed and started feeding the IMU bullshit
<Iskierka> that's probably not recoverable
<Iskierka> the japanese probe kept contact, though - was still under control but lacked the power to enter appropriate orbit
<NCommander> The international expensive hardware lob is the only sport I really enjoy
